2 independent studies validate American Rare Earths' (ARR) Halleck Creek Project, showcasing economic potential. 80% of rare earth elements (REEs) extracted with low-temperature, direct acid leaching, with Halleck Creek's metamict allanite structure allowing fast leaching kinetics. Halleck Creek ore is less refractory than monazite or bastnaesite, and density & magnetic separation techniques demonstrate effectiveness in separation.
